Technically get_dive(i) could return a nullptr. But given the range for i that
can never happen. Still, the test is extremely cheap and doesn't hurt.

When moving dives between trips, the core moves the dives internally
and sends a signal to the model. The model adds and removes the dives
accordingly. However, when adding the new dive, the old trip hasn't
changed its position, so the ordering is wrong leading to an inconsistent
state.
Therefore, remove the dives first and then readd them. There could
still be pathological cases where this fails. However, in the short
term this is an improvement. Note that in similar cases, the dives were
indeed removed then added, so this case here seems to be an oversight.

The get_trip_date_string() formatted, as the name implies, the date
of a trip. It was passed a number of parameters and had only one
caller, which would also add the location if it existed.
Therefore, move all that logic into the helper function and
name it get_trip_string().

If the dive timestamp changes, the dive could move in the dive list. But the
current dive actually doesn't change (it's still the same dive, right?). Yet
we need to update the dive list as well as the shown dive (especially if this
is after adding a dive, which is first inserted with the current time and then
updated with whatever the user enters).

At some time, when introducing the global reset signal the filter
stopped being reloaded when loading a new log. This leads to very
strange UI behavior: dives disappear when editing fields unrelated
to the filter.
Therefore, when reloading the model, reset the filter. One might
argue whether this is the correct place. On the other hand, we
might even make the filter a sub-object of the dive-list model.
Let's think about this.

To reset the core data structures, the mobile and desktop UIs
were calling into the dive-list models, which then reset the
core data structures, themselves and the unrelated
locationinformation model. The UI code then reset various other
things, such as the TankInformation model or the map. . This was
unsatisfying from a control-flow perspective, as the models should
display the core data, not act on it. Moreover, this meant lots
of intricate intermodule-dependencies.
Thus, straighten up the control flow: give the C core the
possibility to send a "all data reset" event. And do that
in those functions that reset the core data structures.
Let each module react to this event by itself. This removes
inter-module dependencies. For example, the MainWindow now
doesn't have to reset the TankInfoModel or the MapWidget.
Then, to reset the core data structures, let the UI code
simply directly call the respective core functions.

For consistency with equipment, use our table macros for pictures.
Generally tables (arrays) are preferred over linked lists, because

Sadly, our table macros are quite messy and need some revamping.

In 9310d72943, resetting of the dive
sites was moved to DiveTripModelBase::reset(). This seemed like a
good idea, because it means that the location list is reloaded
every time the dive list is reset.
Unfortunately that function is only used on mobile, thus on desktop
the dive site model is not updated. Do that in
MultiFilterSortModel::resetModel(), because this is always called
when the dive list is reset. Desktop differs from mobile in that
two different models are used depending on whether we are in list
or in tree mode.

When initializing the fulltext-cache and the dive-list, every
100 dives a notification was shown. I had a feeling that this
made startup significantly slower, but that could have been
purely psychological.
Therefore I measured and indeed, removing the fine-grained
notification, it becomes *significantly* faster. For a 3500
dives test log with mobile-on-desktop:
Initialization of the fulltext: 1350 ms -> 730 ms (-46%)
Initialization of the divelistmodel: 689 ms -> 113 ms (-83%)
Let's remove the fine-grained notification. There *is* a visual

To mark invalid dives, we use a struck-out font, which was a static
variable at translation unit scope, i.e. initialized at application
startup. Sadly, this crashes on iOS.
It is unclear when we can initialize fonts. Try to move initialization
to the constructore of DiveTripModelBase and make the font a member
of that class. For consistency, also make the invalidBrush a member
of this class.
This now means that the diveData function cannot be static anymore,
since it needs access to the font and brush. But OK.

When the dive list is cleared or updated, the entries in the
divesite-model become stale and therefore the divesite-model
(with the actual name LocationInformationModel) also must be
updated. This was done manually in some parts of the code and
forgotten in others. Therefore, do it directly in the clear()
and reset() function of the dive list-model.
This might be a bit of a layering violation: why should one
model call into another if they are not in parent/child
relationship? However, this seems easier than introducing
a global "reset dives" function that coordinates the models.
Moreover, it does not appear 100% safe: if the clearing of
the divesite model causes accesses to the divelist-model,
they happen in the midst of a model reset and we had horrible
bugs with that kind of things. However, I don't think that
should happen.

The DiveFilter class defined the showDive() function to test
whether a dive should be filtered or not. This was used in
DiveTripModel to loop over all dives or all dives affected by
an editing action.
This restricts us in how we do filtering: We can't use indexes
that give us directly the result. To make the filtering more
flexible, move the actual loops that do the filtering to
the DiveFilter class.
The undo-commands likewise called directly the showDive()
function to check whether newly added dives are shown.

We use a QFilterProxyModel to filter out dives that are hidden
according to the current filter-criterion. Instead, filter the
dives already at the DiveTripModel level. Filter out hidden
dives immediately when receiving them. The only difficult case
is when dives are changed, because then visibility can change.
This means that we have three cases to consider:
1) Visibility unchanged -> send change signal
2) Change from hidden to unhidden -> add dives to model
3) Change from unhidden to hidden -> remove dives from model
Things get complicated by the fact that the tree-version of
the model might have to add/remove full trips!
